NKit

WIP!!

NKit documentation is WIP, once released this documentation will be fleshed out and cover as much as possible...

Overview

NKit is a Nintendo ToolKit that can Recover and Preserve Wii and GameCube disc images

Recovery is the ability to rebuild source images to match the known good images verified by Redump

Preserve is the ability to shrink any image and convert it back to the source iso

NKit can convert to ISO and NKit format. The NKit format is designed to shrink an image to it's smallest while ensuring it can be restored back to the original source data. NKit images are also playable by Dolphin
